GASKET Filed Jan., 1'7, 1930 Patented Sept. 15, I931 UNITED" STATES PTATENT OFFICE JOHN H. VICTOR, OF EVANSTON, ILLINOIS, ASSIGNOR TO VICTOR MANUFACTURING & i GASKET COMPANY, OF CHICAGO, ILLINOIS, A GQRPORATION OF ILLINOIS GASKET Application filed January 17, 1980. Serial No. 421,567.

This invention relates to gaskets and it is particularly useful in gaskets of comparatively large size and which have narrow transverse sections like the gaskets employed for sealingthe joint between the head and the block of an internal v combustion engine. These engines now generally comprise six'or eight cylinders arranged in alinement and as close together as they can be made, with the result that the gasket often has many narrow sections which are subjected to reat pressure and strains in high compression motors. The gaskets are usually made in one pieceand ,they are not only provided with large cylin der openings but also with many water clrculation openings andbolt openings, with the result that the relatively large gasket is fragile in structure and may be easil distorted in shipping and handling. It is ighly im- 0 portant that the gasket should be maintained in its original fiat condition of uniform thick ness and that it should be capable of conforming to any irregularity or unevenness in the facesof the head and block to seal the joint, and that it should withstand the extremes of motor heat and pressure.

The invention has for its object to provide a novel gasket for these and other purposes which has the stability required for maintaining it during shipping and handlin in proper condition for use, which will e ectively seal the joint to which it is applied, and which will resist the stresses and strains of continuous operation under the conditions of lheavy loads, high speed and extreme motor eat. A.

A more particularb bject of the invention is to reinforce and strengthen the gasket in a novel manner so that at its narrowest sections 40 it will be capable of resisting the extremes of motor heat and pressure under the most severe conditions.

With these and other ends in view I have illustrated the invention in gasket provided with referring thereto.

cylinder openings and an engine head Fig. 3 is an enlarged sectional view on the line'3-3 of Fig. 2.'

Referring to the drawings the gasket 5 has a plurality of'cylinder openings 6, water circulation openings 7, bolt openings 8 and water ports 9. The cylinder openings are located close together to conform with the block construction and they provide a number of narrow sections as indicated at line 3-3 of Fig. 2. The gasket comprises two outer or facing members or layers 10, 11 which are stamped from thin sheet metal, preferably copper, and an intermediate core or layer or filler 12 of refractory material, preferably asbestos, is interposed between the facing members. The invention thus far described may be made in accordance with Frank J. Ovens Patent No. 1,472,133 patented October 30, 1923, or other forms. The modern high-compression engines re 70 quire gaskets of exceptional efficiency to resist the high heat and severe strains .to which they are subjected and provide an efficient seal. This is particularly true because the cylinders are located closetogether and the gasket necessarily has many very small cross sections. which are liable to beburned or blown out unless they are reinforced and strengthened to resist these severe conditions. The section indicated at the line 33 is'a narrow section located between two cylinders and is one subjected to the most severe conditions of heat and pressure. The head is bolted tightly to the block upon the interosed gasket but, notwithstanding this, the ngine pressure may be so great as to shift this narrow section bodily and laterally unless it is properly reinforced, and this shiftmg, of course, will result in destructive damage to the gasket by burning or cutting. Therefore, I provide two reinforcing layers 13, 14 stamped from thin sheet metal, preferably steel, which are arranged within the gasket between the facings 10, 11 and on opposite side of the core 12. The facings 10, 11, the core 12, and the reinforcing layers 13, 14 are stamped with openings which will perfectly aline when these parts are assembled in the complete gasket and the parts are held together withsuflicient rigidity by the overlapping beads 15 to retain the parts in their proper relative position. .In addition to the beads 15 about the cylinder openings 6 some of the smaller openings, as 7, may be provided with similar beads 16 and these beads will co-operate with the beads 15 to maintain the parts of the gasket in rigid 4 alinement. It is highly desirable that the gasket should be flexible and yielding in order. thatit may conform with any irregularities or unevenness at the contact surfaces of the head and the block, but it should also be sufficiently stiff and rigid to keep the gasket in flat condition free from bends, wrinkles or other distortions, and itmust have resisting qualities sufficient to enable its weakest sections to withstand the severe strains of continuous operation under heavy loads, hi h speed and extreme motor heat. The mo ern development of internal combustion engines has been in the direction of higher pressure and refinements of construction which bring the cylinders closer together and thereby make it-necessary to provide very narrow sections in the gasket. These sections are usually located between cylinders'and they are subjected at both edges to the extremes of heat and pressure. The result is that the gasket must be reinforced and strengthened not only to resist the usual acform, construction and arrangement of parts to adapt the invention for different uses with-' layers having registering openings, and

means securing said parts together.

tion of heat and pressure but also to prevent narrow sections of the gasket from being shifted laterally by the high pressures developed. Some fuels for internal combustion engines create more heat than others and some engines are frequently required to 0perate under unusually strenuous conditions, and these conditions require greater service and efliciency on the part of the gaskets, The present invention satisfies these requirements and provides reinforcements which greatly strengthen the gasket laterally and particularly at its narrowest sectionsand which increase the flexibility of the gasket and 1 at the same time make the gasket sufliciently rigid'to prevent distortion in shipping and handling. The arrangement of the reinforcing layers on opposite sides of the relatively soft core and in contact with the facings is of importance because it provides for an even distribution of heat, pre-x serves the yielding cushion quality of the copper facings and the core, and distributes the reinforcement of the gasket throughout the body thereof. This arrangement pro- I vides a Well-balanced gasket with the reinforcement evenly distributed there through "which makes it especially desirable for use in gaskets of large skeleton formation, with 0 many openings and narrow sections. I have shown the invention in this form in the drawings but it is also useful in other forms of 1 'large gaskets, as well as in smaller gaskets,

such as those employed in the engine ex- 55 haust; and changes may be made in the
